Tropical forests are typically biodiversity hotspots and are usually filled with endemic species. The Upper Amazonia/Guyana Shield, the Congo Basin, and the New Guinea/Melanesian Islands have the highest number of endemic terrestrial (land-living) species on Earth .
What part of the world has the most biodiversity hotspots?
The Andes Mountains Tropical Hotspot is the world’s most diverse hotspot. About one-sixth of all plant species in the world live in this region. The New Zealand archipelago is another hotspot. Life on New Zealand evolved in isolation, so the islands contain many species not found anywhere else.
Where is biodiversity mostly found?
Species richness is greatest in tropical ecosystems. Tropical rain forests on land and coral reefs in marine systems are among the most biologically diverse ecosystems on Earth and have become the focus of popular attention.
Where are the hotspots found?
A frequently-used hypothesis suggests that hotspots form over exceptionally hot regions in the mantle, which is the hot, flowing layer of the Earth beneath the crust. Mantle rock in those extra-hot regions is more buoyant than the surrounding rocks, so it rises through the mantle and crust to erupt at the surface.
Which country has more than one hotspots in biodiversity?
Countries with more biodiversity in the world
For its part, in Asia, the countries with the greatest bio-diversity are China, Indonesia, India, Philippines and Malaysia. In Africa, Madagascar, Democratic Republic of Congo and South Africa.
Which region of the Earth has the greatest biodiversity on Earth?
Amazon rain forest has the greatest biodiversity on planet.
Which country has the highest biodiversity in Asia?
In Asia, the countries with the greatest biodiversity are China, India, Indonesia, Philippines and Malaysia. South Africa, Madagascar and the Democratic Republic of Congo are the most biodiverse nations of the African continent.

Which is the largest biodiversity hotspot in India?
The Indo-Burma region, one of the largest hotspots, covers Myanmar, Thailand, Cambodia, Vietnam, Laos PDR and also includes the Gangetic plains, areas around the Brahmaputra river and parts of Andaman and Nicobar Islands.
How many total biodiversity hotspots are present throughout the world Mcq?
In all, there are 34 biodiversity hotspots present throughout the world.
How many biodiversity hotspots are there in Assam?
Assam has the distinction of having 2 UNESCO World Heritage sites (Manas and Kaziranga) 2 Biosphere Reserves (Dibru-Saikhowa and Manas) 4 Tiger Reserves (Kaziranga, Manas, Nameri and Rajib Gandhi Orang National Parks) and 5 Elephant Reserves.
How many biodiversity hotspots are there in Pakistan?
As a consequence of these geographical and climatic factors, Pakistan has been divided into 10 major ecological or vegetative zones.
How many hotspots are there in India?
India has four biodiversity hotspots, i.e., Eastern Himalayas, Western Himalayas, Western Ghats and Andaman and Nicobar Islands.
How many hotspots have been identified in the world?
There are currently 36 recognized biodiversity hotspots. These are Earth’s most biologically rich—yet threatened—terrestrial regions. To qualify as a biodiversity hotspot, an area must meet two strict criteria: Contain at least 1,500 species of vascular plants found nowhere else on Earth (known as “endemic” species).
Why is the most biodiversity found near the equator?
There might be more biodiversity near the equator because it’s warmer year round, allowing organisms to continue growing. Locations away from the equator will have cold winters that will slow growth for microorganisms, plants and animals.
Which country has the lowest biodiversity?
This is causing species around the planet to decline at a concerning speed. A new analysis looking into how much biodiversity is left in different countries around the world has shown that the UK has some of the lowest amounts of biodiversity remaining.
